Hard to Cheat: A Turing Test based on Answering Questions about Images
Progress in language and image understanding by machines has sparkled the
interest of the research community in more open-ended, holistic tasks, and
refueled an old AI dream of building intelligent machines. We discuss a few
prominent challenges that characterize such holistic tasks and argue for
"question answering about images" as a particular appealing instance of such a
holistic task. In particular, we point out that it is a version of a Turing
Test that is likely to be more robust to over-interpretations and contrast it
with tasks like grounding and generation of descriptions. Finally, we discuss
tools to measure progress in this field.Comment: Presented in AAAI-15 Workshop: Beyond the Turing Tes
Vector lattice covers of ideals and bands in pre-Riesz spaces
Pre-Riesz spaces are ordered vector spaces which can be order densely
embedded into vector lattices, their so-called vector lattice covers. Given a
vector lattice cover for a pre-Riesz space , we address the question how
to find vector lattice covers for subspaces of , such as ideals and bands.
We provide conditions such that for a directed ideal in its smallest
extension ideal in is a vector lattice cover. We show a criterion for bands
in and their extension bands in as well. Moreover, we state properties
of ideals and bands in which are generated by sets, and of their extensions
in
